SPECIFICATION forming part of Let-ters Patent No. 615,014, dated November 29, 189s-,

Application iiled March 17, 1898.

To all wtfmt it ntcty concern:

Beit known that I, WINTHROP M CHAP- MAN, of Needham, county of Norfolk, and State of Massachusetts, have invented an Improvement in Repeaters, of which the following description, in connection With the accompanying drawings, is a specification, like letters and gures on the drawings representing like parts.

The present invention relates to electric signaling apparatus and is embodied in a repeater especially adapted for use in fire-alarm systems.

The object of the invention is to automatically receive and transmit signals Where the signaling instruments are adapted to operate at one rate of speed and it is desired to transmit the signals at a different rate of speed.

In fire-alarm systems it is desirable to have the signals given as rapidly as possible; but in a great many systems steam-Whistles and heavyT mechanism for striking large bells are used in connection with other smaller apparatus for giving alarms. The steam-Whistles and bell-strikers cannot be made to Work very rapidly, and as a consequence the rest of the apparatus in the system which is capable `of acting much more rapidly has of necessity been timed to correspond to the requirements of the slower-acting machines. In accordance With the present invention, however, all the apparatus that is capable of operating quickly may be so operated and the sloweroperating machines need not be dispensed With, but may be operated by the slower'- transmitting mechanism which operates in response to the quick-operating devices. It can be so arranged that both the Whistles, the., and the smaller gongs, dac., may be located in the same circuit or in separate circuits, as desired, and it may be connected with one or several circuits.

The instrument embodying the invention consists of a main controlling device adapted to operate in response to the impulses of signals received at the instrument, the said controlling device being adapted to act at each impulse so as to cause the operation of a device for setting a number ot' movable parts in position to cooperate with a signal-repeating train capable of operating at any desired speed and to produce changes in a signaling Serial No. 6741176. (No model.)

circuit or circuits by such cooperation, thereby transmitting the signal at any desired speed. The signaling-train is arranged to be released by the said controlling device at the first impulse of the signal and to continue operating until the entire signal has been repeated.

For convenience I will term the movable parts which cooperate with the signal-repeating train recording-arms, since' they practically record the signal which comes in from the boxes in order that it may be transmitted by the signal devices as recorded. These recording-arms are arranged consecutively and are adjusted to the path of a traveling actuator, which is adapted at each impulse of a signal to engage one of said recording-arms and move the same to its operative position. The said traveling actuator is provided with an escapement device, whereby it is caused to move only a certain predetermined distance at each signal impulse,and thus consecutively act upon certain recording-arms to set or move the same. In order to provide for the longer intervals between the groups and rounds of a signal, the said'escapement device which controls the actuator is also movable and is itself controlled in its movement by a timing device, Which permits the said escapement, bearing With it the traveling actuator, to move a certain predetermined distance at each interval longer than the interval between successive impulses of a single group. The said controlling device is of novel construction and forms a feature of the present invention. Thesignal-repeating mechanism comprises a movable member carrying a circuit-controlling device and adapted to move said circuit-controlling device in a path adjacent to the path of the recording-arms, so that said circuit-controlling device may engage with such of the recording-arms as have been moved by the actuator into their operative position. Thus as a signal is received the actuator will cause recordingarms corresponding in number and spacing to the impulses of the signal received to be moved into their abnormal or operative position, andthe signal-repeatin g mechanism, which is started at the first impulse of the signal, follows at any desired speed and repeats the signal which has been thus recorded.

IOO

The invention further relates to a timing device of novel construction and arrangement, which will be hereinafter more fully described.

Figure 1 shows a front elevation of an apparatus embodying the present invention used in conjunction with an ordinary {irealarni repeater, the slow-moving repeating mechanism being for the most part indicated in dotted lines. Fig. 2 isa plan view of that part of t-he mechanism embodying the present invention, which is shown in Fig. 1 above the dotted line A B, some of the parts being shown in section and only two recording-arms being shown. Fig. 3 is a sectional front elevation of the mechanism shown in Fig. 2, the section being mainly taken on the dotted line O D, the slow-moving arm and attached parts, however, being shown in elevation. Fig. 4 shows a front elevation of the apparatus similar to Fig. l, (it being shown in this instance as an independent machine and not in combination with an ordinary repeater,) but with the parts in the relative positions they will occupy after the first impulse of a signal has been received. Figs. 5, G, and 7 are details to be referred to. Figs. 8, 9, 10, 1l, 12, and 14 are modifications to be referred to; and Fig. 13 is a detail in elevation, showing a timing device of novel construction, which forms part of the present invention.

Then the machine is used in connection with and as a part of a regular repeater, as shown in Fig. 1, the regular repeater motor or train (indicated by dotted pitch-circles in the lower left-hand part of Fig. 1) serves to actuate the recording mechanism of the present invention and to control the signaling mechanism. The repeater shown will not be herein described in detail, since it forms no part of the present invention. For convenience I have shown a repeater like that described in a prior patent granted to me January 12, 1897, No. 575,025. It is obvious, however, that the mechanism embodying the present invent-ion may be used with any repeater or independently, as indicated in Fig. t.

As Shown in Fig. 1, the repeater-train, which, as stated, serves to actuate the recording mechanism, is controlled by a movable arm S, cooperating with a stop-arm b' in the usual way. lVhere a rigid stop-arm of this kind is used, however, the impact of the moving member controlled thereby at the end of a revolution is sufiicient to cause a detrimental shock, so that the parts are quickly worn out or gotten out of adjustment, and this defeet may be obviated by providing the stoparm S with a cushioned engaging member z, as shown in Fig. 11, the said member being cushioned in any suitable way, as by the Spring s.

XVhen the machine is used as a separate mechanism independent of a regular repeater, as shown in Fig. 4, an electromagnet d, connected into a signaling-circuit (not shown) and responsive to the impulses of signals, serves to control a motor or train for the same purpose as the repeater-train in Fig. 1. The said electromagnet a is provided with an armature a', secured to a holding-arm a2, pivoted to one side of the frame E of the machine at d3. The locking projections a4 and a5 are secured to and movable with the armatureholding arm a2 and constitute a double detent of the usual type for the signaling-incohanism controller.

A retractile spring a serves to move the armature a into its retracted position, when the magnet a becomes demagnetized. A snitable motor, such as the train of wheels indicated by dotted circles on the left lower part of Fig. 4, is adapted to rotate the shaft ZJ of the controlling mechanism above described in the direction of the arrow. An arm b/ is secured to this shaft Z), and a projection b2 is formed on the end of said arm b and, together with the projections a4 and a, forms the releasing device controlled by the electromagnet d of the mechanism shown in Fig. Lt. A cam c (shown by dotted lines) is secured to the shaftb and is adapted to engage a roll on the end of an arm c and so wind up a timetrain or timing device (indicated by dotted lines) on the right-hand side of the electromagnet c. An eccentric-pin cl is formed on the front end of the shaft b, and as said shaft b revolves at each impulse of a signal this eccentric-pin d, by means of suitable connecting parts, controls the mechanism shown in the upper parts of Figs. 1 and Lt.

The lower end of a connecting-rod CZ is con nected tothe eccentric-pin (l, and its upper end is connected to the end of one member c (see Fig. 7) of a bell-crank lever e e', pivoted at e2 in a holding-piece c3, secured to the main frame E of the machine. One end of another connecting-rod e4 is connected loosely with and free to turn in the end of the member e.' of the bell-crank lever pivoted at e2. The other end of said rod c'1 is loosely connected at e5 (see Figs. 2 and 7) with the rocking ac tuating-arm and is adapted to actuate the same, as will be described.

A hollow stud f is fastened securely into the back side of the frame E, and the connecting-rod e4 passes freely through the hole in the center of said stud f. A crown ratchetwheel f is loosely pivoted and free to turn on the stud f. Said ratchet-wheel fl is provided with any suitable number of teeth on one of its faces and with pins on the other, there being shown herein sixty teeth and twenty pins f, arranged at equal distances from each other on its other face. A carrying-piece g is also loosely pivoted to and free to turn on the stud f, and said carrier g has a rocking arm g', pivoted on it at (2, the said rocking arm constituting the actuating-arm, as stated. The said arm g is provided at or near its extremities with two projections g3 and g4, said projections being adapted to alternately engage with the teeth f2 of the ICO IIC

tance beyond the pivot g2, and said arm g6i carries a roll g'v at its extremity. At the opposite extremity from the roll g7 the carryingpiece g is turned at right angles, as at g8, and

said part gB is slottedand acts merely as an eXtra guide for the rocking arm g. A bridging-piece gf, formed integral with the rest of the carrying-piece g, extends from the turned portion g8 to a corresponding portion near the pivot g2, and said bridging-piece Q9 serves merely to carry a stud glo and a pin gn. (See Figs. 2 and 1l.)

' A support for the movable recording-arms, herein shown as a ring 7i, is secured rigidly to the back side of the frame E by means of the three supporting-studs 3, Figs. l and t, said support being concentric with the crown ratchet-wheel f. Secured to the back side of the ring h are a number of holding-blocks 7i', arranged at equal distances from each other around said ring h, and each one of these holdin g-blocks h carries a movable recordingarm h2, loosely pivoted to it at h3, Figs. 2 and 5. For clearness only a few of these recording-arms h2 are shown in most of the views. The said recording-arms h2 are provided at one end with engaging portions h4 to coperate with the rocking recording-arm g' and at the other end with engaging portions h5 to cooperate with the signaling mechanism, as will be hereinafter shown. of the recording-arms are arranged in position to be successively acted on and moved from their normal to their abnormal position by the extension-piece g5 on the rocking arm g' as said rocking arm g is rocked in one direction. In order that said recording-arms may be held in either their normal or abnormal positions when moved into either, they are shown in Fig. 5 as provided with V-shaped projections h6, cooperating with plugs 77,7, provided with springs hs, thus constituting practically a snap locking device, which will not only hold the arms in either position, but will tend to carry them from a central position to either cxtreme position if sufficient impulse is given to move them across the center. It is practicable, however, to accomplish substantially the same purpose by frictionally supporting the said arms on their pivots, such a construction being shown in Fig. 8,wherein the arms h2 are pivoted between a pair of ears or lugs which are near enough together to frictionally engage the opposite sides of the sai-d arm and prevent the same from being accidentally moved in either direction.

A segment t' is pivoted to the frame E, and

said segment 'i is connected by means of a con-Y necting-rod t" to the arm c' of the time-train. (Shown in the lower left hand of Figs. 1 and The said portions 71:1`

4.) The flange i12 of said segment iis so disposed as to be in the path of and adapted to engage the pinsf3 on the front side of the crown ratchet-wheel f Two gaps 3 and 4 are cut through this fiange 2, and two light fiat springs 5 and i are secured to the inner side of the said flange i2 (see Fig. 6) and are arranged, respectively, to bridge the gaps 713 and t, the free ends standing normally far enough away from the flange to permit the pins f3 to pass between them and the iange. Vhen the time-train after being wound up has run down a sufficient distance, the segment z' has reached such a position as to allow one of the pins f 3,which is in engagement wit-h the flange i2, to pass under the loose end of one of the springs 5 i6, and so pass through one of the gaps is 4. This allows the crown ratchetwheel to be rotated the distance between two .of the pins f3, as the succeeding pin will engage one of the springs 5 i, and so be prevented from passing through the corresponding gap in the ange The time-train shown in Fig. 4 is of the usual type, an electromagnet a being adapted to control the action of a train of wheels adapted to rotate a shaft b, and thereby, by means of an eccentric-pin d, to give motion to the connecting-rod d. This main train of wheels is also adapted to wind up a time-train. A timing device of novel construction and arrangement, however, is herein shown and forms a feature of the present invention. In this construction, which is shown in Fig. 13, the main train of wheels is entirely dispensed with,motion being given to the connectingrod d directly from the action of the electromagnet d and the winding of the time-train being accomplished in another way. As shown in Fig. 13, the electromagnet is provided with an armature d', fast to a holdingpiece d2, pivoted at a3 and provided with a retractile spring a6. Two arms w w' are formed integral with the armature-holding piece a2. As the armature a is retracted by the spring d6 the end of the arm 1U engages with a spring-pressed pawl w2, secured to an arm w3, pivoted at 104. The lower end of the .connecting-rod d is also loosely secured to the arm w3, and as the arm w, engaging the pawl 102, swings the arm w3 downward a downward motion is also imparted to the connect'- ing-rod CZ. After the arm w3 has been swung downward a sufficient distance the end of the arm w disengages from the pawl 102 and a spring @U5 swings the arm w3,and consequently the connecting-rod d', upward to its original position,th us completing the motion of the rod d. The winding of the time-train may be accomplished in several different ways, and in Fig. 13 this is shown as being done by the action of the shaft Z3 in rotating. An arm a: is

made fast to the wheel Z4 and is adapted at each revolution of the shaft Z3 to engage with one of a number of pins or. These pins 0c' are secured at equal distances from each other in a wheel gandprojectlaterally therefrom. This v IOO IIO

pin-bearing wheel .t2 is pivoted loosely on a shaft afg, and one end of a spring at" is secured to said wheel at the other end of said spring being fast to the shaft A ratchetwheel af (shown in dotted lines) is secured rigidly to the frame of the machine, and a pawl it?, pivoted to the wheel fr?, is adapted to engage the teeth of said ratchet-wheel 050. As the spring .t4 is liable at times to be wound up faster than it runs down, suitable means are provided to prevent it being overwound. These consist of a segment of a wheel x8, secured on the shaft co3, and a pin 0c in the end of the pawl Then the spring a4 is wound up a certain distance by the action of the projection it on the pins the pin 009 will becolne engaged with the segment x8 and so raise the pawl out of engagement with the ratchetwheel c6 and so prevent further winding. The action of the springrr4 in unwinding tends to rotate a ratchet-wheel g/ in the direction of the arrow. An arm y is loosely pivoted concentric with the ratchet-wheel y, and a pawl y2 is pivoted on said arm y at ,1J/3. In its normal condition the pawl y2 engages the teeth of the ratchet-wheel y, and the time-train is brought to rest and held in its normal position by the arm y' engaging a pin y/'i on the frame of the machine. A pawl y is loosely pivotcd at if to a suitably-flattened portion of a sliding rod I/S, arranged to slide freely in two guiding-pieces 1/f and gjm, secured to a suitable part of the frame of the machine. (Not herein shown.) The connecting-rod U12 is loosely pivoted at one end to the pawl y2 and at the other end to the iiattened portion of the sliding rod Us. Vhen the armature a/ is retracted by the spring a, the arm w engages the pawl 1/5 and causes a sliding movement of the rod ys, which is transmitted through the rod .1/2 to the pawl y2, forcing the said pawl 1/2 out of engagement with the teeth of the ratchet-wheel y. As the pawl ,if2 is thus disengaged a spring y, acting on the arm y1f, swings said arm 1, and also the arm yy' and attached parts upward, and the spring cc is free to rotate the ratchet-wheel g/ and the rest of the time-train. After being disengaged from the ratchet-teeth the pawl U2 is held out of engagement until as the arm y is moved upward the end of the pawl y2 engages with a beveled block p60 on the frame and is swung back, so that it can engage the teeth of the ratchet-wheel y. The arm y will now be moved downward with the ratchet-wheel gj, and as the rod t" connects the arm y with the arm the said arm i will be moved also. This arm corresponds to the segment t' in the main drawings and its motion serves to release the pins f3, as in the main drawings. At each impulse of a signal the pawl y2 will be disengaged and swung upward, as above described, but will finally come to rest after the completion of a signal as the arm y' engages the pin y* in the frame.

The operation of the device as thus far described is substantially as follows: Upon an impulse of a signal the motor-shaft l; makes one revolution, rocking the recording-arm actuator g forward and back. Such rocking movement, as described, causes the said arm to move one of the recording-arms h2 from its normal to its abnormal position and permits the arm g to rotate a predetermined distance. This operation is repeated at each impulse of the Iirst group of a signal, thus moving a number of said recording-arms equal to the number of impulses in the group, the recordingarms moved beingequidistant from each other. The timing-train is so arranged that the segment i is restored to its normal position at each impulse before it has moved suiiiciently far to permit one of the pins f to reach the opening is in the said segment, so that during the firstgroup the crowntoothed wheel f is retained stationary. At the end of the group, however, the interval between impulses is suliciently long to permit the time-train to run down suiciently far to allow the segment to travel upward, Fig. Ll, and move to such a position that the opening t" comes in line with one of the pins j, thus permitting the crown-toothed wheel f' to rotate until the succeeding pin f is caught by the flange i on the segment t' or the bridging-spring 115. This rotation of the crown-tooth wheel carries with it the arm g', so that at the next impulse the said arm will actuate a recording-arm at a distance from the last recording-arm moved which corresponds to the interval between the groups of the original signal. During the longer interval between complete rounds of a signal the segment c' will be moved sufliciently far to permit the pin f3, which is engaged beyond the opening is, to pass through the opening 4, thus producing a still greater interval between the recording-arms which have been moved. The same operation continues throughout the complete signal, so that the recording-arms are set ready to coperate with the signaling mechanism, which will be hereinafter described, in such a manner that the signal is repeated by the said signaling mechanism at any predetermined speed.

The signaling mechanism consists, essentially, of a movable member actuated by a motor or train, which is normally held stationary, but released in response to the first impulse of a signal. The said movable member is provided with a device to cooperate with the recording-arms which have been moved, as above described, from their normal to their abnormal position, said device controlling the circuits over which the signal is to be repeated, so that each time said movable member is actuated by coming in contact with one of said arms it causes a change in the said circuit or circuits. This may be accomplished in any suitable or usual way, the circuit changes being either caused directly by the action of the said movable member or by a secondary motor controlled thereby.

IIO

The construction and arrangement herein shown to illustrate the invention are substantially as follows:

Referring to Fig. 2, it Will be seen that the main frame of the machine is provided (in addition to the front plate E) with corresponding plates 'F and G, all three of said plates being secured together by suitable studs.

In Figs. l and t that part of the mechanism shown back of the dotted line O D in Fig. 2 is for the most part shown merely by dotted pitch lines to indicate the train of Wheels, so as to avoid a multiplicity of lines. These parts are, however, clearly shown in Fig. 3, which is a sectional elevation taken on the line C D, Fig. 2. A Winding-shaft has its bearings in the main frame-plates E and F, and a Winding-pinion 70 is secured thereto and meshes with a corresponding windingpinion 702, secured to a shaft 702. The said shaft 703 has its-bearings in the main frameplates F and G, and two driving-wheels 704 and 70 are loosely mounted thereon. The driving-Wheel 704 is provided With a suitable pawl arranged to engage the teeth of a Winding ratchet-Wheel 706, secured to the shaft 703. The driving-Wheel 705 is secured to a springbox 701, which incloses a suitable drivingspring. One end of the said driving-spring is secured to the spring-box 707 and the other end is made fast to the shaft 702. This arrangement allows the drivin g-spring to rotate the Wheel 701in one direction and the Wheel 705 in the opposite direction, and also allows either of the Wheels 704 or 705 to revolve While the other is stationary. The Wheel 704 meshes with a pinion 70S, secu red to a shaft 709, to which a Wheel 7010 is also secured. This Wheel 7010 meshes with a pinion 7011, secured to a shaft 7012, to which a Wheel 7013 is also secured. This wheel 7013 meshes AWith a pinion 7014 on a shaft h1, to which an escape-Wheel 7016 is also secured, said escape-Wheel 7016 engaging with a suitable pallet or escapement 7011, adapted to regulate the motion of the train of Wheels. The driving-Wheel 705 meshes with a suitable pinion Z, secured to a shaft 7', having a wheel Z2 also secured to it. Said Wheel Z2 meshes with a suitable pinion secured to a shaft Z2, having also a wheel Z4 secured to it. The Wheel Z4 meshes With a suitable pinion on a shaft Z5, to which a fan Z6, adapted to regulate the motion of the train of Wheels, is secured. An arm m is secured to the shaft 7012 on the front side of the main frame-plate F and has formed on it a lookin g projection m', said projection m/ being adapted normally to engage with a suitable part of the carrying-piece g near the pivot g2, and so prevent the shaft 7012, bearing the arm m, from revolving. A roll m2 is shown as secured to a suitable projection on the arm m, and a movable paWl m2 is also loosely pivoted to said arm m at m4. The said pawl m2 has a beveled portion m5, Fig. 1, formed near its extremity, and said beveled portion m5 is adapted to engage with the movable recording-arms 712 when said arms 77.2 are in their abnormal positions, and to thereby cause a movement of the pawl. As said paWl m3 disengages one of the arms h2 after being actuated thereby the roll m2 engages with said arm h2 and causes it to be moved back to its original or normal position. The roll gl is so disposed on the extensionarm g of the carrying-piece g as to move adjacent to the arms 712 and just ahead of the actuating-arm g, and if through any cause any of the arms 7b2 should be left in their abnormal position the said roll g7 Will act similarly to the roll m2 and restore them to their normal positions. It may be desirable in some cases to have the arms remain in their abnormal positions between signals, and in this instance the rolls m2 may be omitted. The paWl m2 is also loosely connected at m6 With one end of a connecting-rod m7, Fig. 3, the other end of said rod m7 being connected loosely at n to one member n of a bell-crank lever vn' n2. A slot n2 is formed in the arm m, and in this slot n2 the bell-crank lever ot' is pivoted at n4. The shaft 7012 has a central longitudinal opening from end to end, and a connecting-rod a5 passes freely through said opening. One end of the said connectingrod a5 is loosely connected with and free to turn in the end of the member n2 of the bellcrank lever n' n2. The other end of the rod a5 is also loosely connected at o to one end bf a releasing-lever o', pivoted at 02 to a suitable holding-piece secured to the back of the main frame-plate G. Two projections 03 and 01 are formed on the opposite end of the releasinglever o. An arm o5 is made fast to the back end of the shaft Z2, and the end of this said arm o5 cooperates with the two projections o3 and o4 on the releasing-lever o, and this forms a releasing device that allows the shaft Z2 to make one revolution each time the pawl m3 on the arm m engages with one of the recording-arms 71,2.

If desired, the circuit-changing devices may be operated directly by the movement of the pawl m3 instead of by a motor controlled by the movement of said pawl. As shown in Fig. 12, the said pawl cooperates directly, as by a rod n, with the circuit-changer, connection being shown as made by means of a lever t, pivoted at t', the members t3 and t4 of the circuit-changer being normally held together by means of a spring t6. The said lever t is provided with a finger-piece or projection t5 coactingdirectly With the spring contact-piece t4, and the rod n in moving overcomes the stress of said spring and permits the contact t4 to be separated from the contact t2, and thus open the circuit, and thereby repeat the signal which has been originally received and recorded.

The circuit-changer is shown as mounted on an arm or standard t2.

To change the circuit in response to the action of the train of Wheels above described, a roll j? of insulating material isshoWn in ICO IIO

Figs. 2 and 3 as firmly secured to the shaft 7.3, and this roll p has a gap p formed in it lengthwise. A block p2 of insulating mat-e rial is secured rigidly to a suitable post fast to the frame-plates F and G, and on'this said block pianumberof circuit-changingsprings p3 and p4 are secured. These springs p3 and p* represent a common circuit-changing device and are so arranged that normally the ends of the springs p3 which overlap the ends of the springs p* stand over the gap p' in the roll p, and so the springs p3 and p4 are allowed to stay in contact. As the shaft Z3 rotates, carrying the roll 2), the higher part of said roll p raises the springs p3 from engagement with the corresponding springs p4, and so causes an impulse to be sent out or transmitted. A pin -1- is secured in the hub of the arm in. A light spring 5 is coiled loosely on the stud gw on the carr ying-piece g, and one end of said spring 5 is secured to the pin g1l and the other end thereof is made fast to the pin 4f on the arm m. This spring 5 does not act as a connection between the slowmoving arm in and the quick-moving receiving parts, as no such connection is needed. It merely serves to actuate the carrying-piece g and is connected to the slowmoving arm m, so that the movement of said arm m may keep the said sprin g 5 continually under tension, and so do away with the necessity of winding it up by hand.

Fig. i) shows in detail a modification of the apparatus shown in Fig. 1, the quick-acting receiving mechanism being actuated and governed by a mechanism similar to the regular repeater mechanism shown in Fig. 1, with the repeating circuit-changers and `coperating parts of the repeater omitted, so that the repeating action of the regular repeater is dispensed with. l

As shown in Fig. 0, the rod d' is connected directly to a part 12 of lthe releasing device for the repeater, its motion being governed by any one of the repeater-magnets, (not shown,) said magnets being connected to the rods 10. In the construction shown in Fig. 0 only one-half as many pins f3 are needed in the ratchet wheel j" as are used in that shown in Fig. 1, and the segment t and its cooperating parts are dispensed with, and an arm r is pivoted at 2, and the upper end of the rod vL" is loosely connected to said arm. The arm r terminates in two projections fr' and r2. On the projection r' two flat springs r3 and r* are secured, and on the projection r2 two corresponding springs T5 and r6 are made fast. An arm ,s is rigidly attached to the inner side of the main frame-plate E, and a movable piece is pivoted to the front side of said arm s at s2. Two pins .s3 and s4 are secured in the movable piece s and extend laterally therefrom, so as to be alternately in the path of movement of the i'lat springs r3, r4, o5, and r on the arm fr. Two other pins $5 and .S6 are also secured in the movable piece s' and extend laterally therefrom and are so disposed on said piece s as to be alternately in position to engage the pin s f3 on the crown ratchet-wheel f Two notches S7 and .SS are formed in the movable piece s' and are adapted to alternately engage with a suitable projection on the end of a spring s, secured to the arm s. W'hen the arm r has been moved downward sufficiently far by the action of the time-train, the end of the iiat spring r3 engages with the pin si on the movable piece s' and swings said piece .5" on its pivot s2 until the pin .s3 has swung out of engagement with the end of the spring r3. This movement has served to swing the movable piece s' sufiiciently far so that the pin s is moved out of engagement with the pins f3 on the ratchet-wheel j", and the pin S6 on said piece s is moved into the path of engagement of the pins f3. This allows the ratchet-wheel f to be rotated half the distance between said pins f3 or until the next succeeding pinf3 engages with the pin s on the movable piece s. The projection on the end of the spring 39, en gaging with either of the notches $7 and s, serves merely to hold the piece s in position. The next movement of the movable piece s will be caused by the action of one of the springs r4 or r6 acting on the pin s4, secured in the movable piece s. This will swing the said piece s back to its original position and allow the ratchet-wheelf to rotate again the distance of three teeth on said wheel f.

If it is desired to have both the quick-acting signal-giving machines, such as small gongs, ttc., and the slow-acting sgnal-giving machines, such as steam-Whistles and large bell-strikers, located in the same circuit, the quick-acting machine may be arranged to respond to breaks and closures in the circuits, such as would be caused by the ordinary circuit-changing contact, as hereinbefore described. The slow-acting machines could then be arranged to respond only to a change in direction of the current in the circuit, or, as it is commonly called, a reversal of the circuit. This may be accomplished by providing the apparatus with any of the common forms of circuit-reversing devices, as indicated in Fig. 10.

In Fig. 11 the projection m', which is engaged by the arm g to hold the signalingtrain normally stationary, is shown as engaging a beveled portion 12 on the said arm r', the object of this being to make the releasing of the arm m easier. A beveled portion on the projection m engages with the beveled part 12 on the rocking arm g', and these beveled parts acting together tend to help move the arm g at its iirst impulse when the arm m is released.
